    Yes, the input drum is a complex piece, see the attached cutaway view from www.transmissioncenter.net (PATC):

    Sounds like a project, but not necessarily commercially viable. I'm building a 454 so if you need a guinea pig to test one out, let me know. ,

    I hear ya - in my case I'm already stuck with the 4L60 because I want to keep the AWD in my Silverado SS; by the time I figured the costs of building a 4L80 conversion versus a custom 4L60 with a $2000 one-off billet drum it will end up about the same :sigh: Plus everyting in my 4L60 is 300M billet now, so I've already got a lot vested in this unit. I won't get to that project until next season at least, I'll decide then as the time gets closer. Or if I grenade something first LOL.

    I must ask. What kind of power and torque do you reckon your 4L60 will take with all your modifications?

    Reason I'm asking is that I can't get a 4L80 into my truck without major surgery, it's quite small compared to what you guys run in the States.

    So I need to build mine as strong as I can. Luckily I've got a brand spanking new 4L65E coming over from Australia at the moment at a really cheap price.

    Any help gratefully received.

    Well if the transmission is for the vehicle in your sig, a well-built 4L65 will happily live; we have a Silverado SS AWD truck here locally that goes 11.8's with one of our 4L65's on a stock LQ9 + bolt-ons + 225-shot right outta the hole!! That's a 5600-lb truck with almost 600-rwhp, I will have to ask about the converter he used but I want to say it was a cheap 3400 stall... The trick with the 4L60 is that it is VERY unforgiving, we have found there is only one certain setup that will work - the build has to be right, the valve body mods have got to be right, and the TUNE has got to be right. AFA how strong my own transmission is, hell who knows... LOL the number that I've been told by a couple persons is 700+, we'll see in time. Remember that vehicle weight is a big factor in transmission life, it's not only that we are throwing 650+ hp at it, but also that we are doing so in a 5600-lb truck; if the vehicle was 2000-lbs lighter (like a vette or fbody) then reliability would be far better I'm sure.

    Your box sounds like an awesome piece of work. I should've said that the new box I have is stock, and we are going to build that. I'm researching finding the right parts to build it strong enough at the moment. I have time because the short motor is 16 weeks away.



    My Ute is only 3300lbs and people have said that I need to ditch the 4L65E. I don't want to do that because of the tuning possibilities with EfiLive, which pound for pound has been the best piece of software I have EVER bought.

    Hey, Thanks for your feed back, it has given me more confidence to persever with what I am doing.

    I downloaded a tune from holden for a 2001 Camaro and D2801 Upshift TCC Lock was set to Yes, is this normal or did someone change it?

    That is the factory stock setting...

    but notice that the TCC is still unlocked at WOT (see the TCC Release tables D1004-D1009).
